Where are the choices?
the answer could be that both parents are carrying the heterozygous genes. so let's say B is the dominant brown eye gene and b is the recessive blue eye gene. both parents could possess the Bb genotype, and hence by using test cross, Tim was that 25% chance where a child could inherit the bb genotype to have blue eyes
Answer:
Dehydration
Explanation:
Dehydration is the condition of the body which involves the loss of body fluid compared to the amount of water the body gets. Water is an important constituent of the human body making up to about two-third of the body. The normal body metabolism is affected when the amount of water in the body drops below the required level of water necessary for optimal functioning of the body.
Athletes usually suffer from dehydration, most especially long distance runners, as they tend to lose a lot of body fluid through sweating while the body tries to regulate the body temperature during the race. When the body is dehydrated, the heart works harder to pump blood to various parts of the body leading to loss of strength of the muscles.
Common signs a dehydrated person shows include feeling tired and lightheaded, loss of body weight etc.

Explanation:
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. ... At each stage of a food chain, most of the chemical energy is converted to other forms such as heat, and does not remain within the ecosystem.
Answer:
Mammals. There are no known cases of naturally occurring mammalian parthenogenesis in the wild. This is because mammals have imprinted genetic regions, where either the maternal or the paternal chromosome is inactivated in the offspring in order for development to proceed normally.
